Puerto ^2co.— December 7, 1936, to January 20, 1937. Stations 345 

 to 359. On this return visit we again made our lieadquarters in 

 San Juan. (See map No. 5.) A very unusual December storm 

 spoiled nearly 2 weeks of our time, and difficulties in obtaining trans- 

 portation to Jamaica took another week. However, collecting was 

 done in the vicinity of El Yunque Peak in rain-forest, along the 

 southern coast, and at the extreme western end of the island. Mr. 

 Oakley and Professor Danforth again kindly assisted in collecting 

 and made our stay much more pleasant and profitable. The total 

 number of species of Staphylinidae collected (exclusive of the Aleo- 

 charinae) was 54. 



/<^m«^V«.— January 22, 1937, to March 6, 1937. Stations 360 to 

 435 (and 444). On this return visit we again established our head- 

 quarters in Kingston but made several more prolonged stops in other 

 parts of the island. Our principal collecting was done in the central 

 and south-central portions and about Kingston, but visits were made 

 also to the north coast, the eastern end of the island, and to various 

 other parts. 



Dr. E. A. Chapin, curator of insects at the United States National 

 Museum, joined us in Jamaica from January 27 to March 6. Inten- 

 sive collecting with renewed enthusiasm resulted in the accumulation 

 of a large collection of Coleoptera, including many thousands of 

 Staphylinidae. Several methods of quantity collecting were em- 

 ployed, and these produced many previously unknown species. Be- 

 cause of the help of Dr. Chapin, Jamaica was much more completely 

 collected than any other island, and we probably know a larger per- 

 centage of its species of Staphylinidae than from any other island. 

 The total number of species collected on the island (exclusive of the 

 Aleocharinae) was 82.
